Philip Elcan d10447e717 gpu: nvgpu: init: make poweron table driven ...

Change nvgpu_finalize_poweron() to call the subunit init functions by
using a table. The table is local to nvgpu_finalize_poweron() since the
function pointers are stored at runtime in the gk20a struct during HAL
init. The table also includes a field for checking an enable flag before
calling the init op, if required.

The primary motivation for this change is to reduce CCM for
nvgpu_finalize_poweron(). This change reduced the TCC metric from 40 to
10.

The init unit test is disabled until it can be updated to match the new
design.
